It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
In order to improve the accuracy of user requirements analysis result, the embodiment of the invention provides a kind of external service called sides
Method, as shown in Figure 1, this method comprises:
101, after receiving input information, according to the data format of request model conversion input information.
In general, when needing to call a service, it is necessary first to determine the solicited message for calling the service, by
Calling between service is realized based on request and response, and therefore, the generation and determination of solicited message just become very
It is important.However, in practical applications, due to system outside service and system in program or function between may be different volume
What Cheng Yuyan write, and all there is difference in code format in these language or data structure, when a service was carrying out
When needing the external service outside calling system in journey, the format of the two code is probably different.Therefore, of the invention real
It applies in external service call method described in example, it is necessary first to convert the format for inputting information to object format.
Wherein, object format described in this step is determined according to request model, and the request model can be silent for system
Recognize, be also possible to according to the needs of users determined by, do not do specific restriction herein, can according to need selection.But
Ensure to request comprising the correlation attribute information required for format conversion in model, so as to according to the request model, really
Surely the data format converted needed for input information, meanwhile, it is also to be ensured that according to the data format energy obtained after request model conversion
Enough systems or program by where called service are identified.Certainly, in this step, the conversion of data format can basis
Mode in the prior art carries out, it is not limited here.
102, the input information after change data format is packaged according to the corresponding request specification of the request model,
It obtains solicited message and sends the solicited message, to call external service.
It in this step, can be according to the request in request model after having carried out format conversion to the input information
Specification is packaged operation to the input information after the conversion, the solicited message after being encapsulated.Specifically, being packaged operation
Mode and program can be executed by preset function or program.Since the solicited message is to be used to call external service
Information, therefore, after obtaining the solicited message, where needing to carry out the solicited message to be sent to corresponding called service
Program or system in so that corresponding service is responded accordingly.
It should be noted that in embodiments of the present invention, in the request model may include information-related with input
The relevant information of attribute information, request specification and canned program, can be according to request model generation pair to input information
The solicited message answered.
103, after receiving the solicited message corresponding response message, the corresponding response specification of model will according to response
The response message is disassembled, and response message segment is obtained.
Purpose due to sending request is to call corresponding service, and its basic goal is to obtain called service
It is obtained as a result, therefore, after the called service feedback response message of corresponding requests information, called side can receive this
The result that external service is fed back.It under normal circumstances, include a large amount of data in the response message of feedback, and among these not
Be all data all be call external service when it is required, and the feedback information be with one encapsulate data packet form deposit
, to obtain internal actually required data, it is also necessary to be disassembled to the response message.Therefore, in this step, may be used
Response message segment to be disassembled the response message by the response specification of response model, after being disassembled.Wherein, originally
The response message data format required when being converted into output information is contained in response model described in inventive embodiments, together
When, it is different based on response specification defined in not homologous ray or program, therefore corresponding different specification has different responses
Model, also just because of this, when model disassembles response message according to response, it is also necessary to according to different response specifications come
Corresponding response model is chosen, certainly, herein specific restriction is not done for the selection of response model, specifically, according further to
Actual conditions select.
104, according to the response model, the data format of the response message segment is converted, obtains output information and defeated
The output information out.
After step 103 dismantling, for the response message segment after dismantling, it is also necessary to carry out the conversion of data format.Tool
Body, as described in step 101, different services may be different what programming language was write in different systems, because
This return data format be also likely to it is distinct with the data format of called side, thus, it is desirable to according to response in model
Attribute information is come the format converted needed for determining.Simultaneously as the data for including in response message are all not the calling of service
Required for side, and the response message data volume may it is larger, therefore, may include in response model attribute information,
For disassemble response message dismantling program and response specification etc. information, so as to receive response message can be according to the sound
Model is answered to carry out dismantling and the conversion of format.
Specifically, during carrying out the dismantling of response message, it is thus necessary to determine that being held by which program during disassembling
Row dismantling behavior, wherein in embodiments of the present invention, can be by defining specific dismantling program in response model.Meanwhile
For different response models, inside the dismantling program that defines may be it is different, this is determined based on different response specifications
It is fixed, it also just so, in embodiments of the present invention can be by defining corresponding dismantling program or disassembling device in response model
To ensure which kind of program to execute the function of dismantling behavior during realization is disassembled by.In addition, after dismantling program has been determined,
Also it needs to be determined that response specification corresponding to response model in this step.Wherein, different response specifications is determined to work as and be received
When different response message, the difference information such as quantity, fragment data amount of the segment after required fractionation.Certainly, for specific
Dismantling mode, dismantling process and indistinction with existing response message, does not do specific restriction, herein to select in actual conditions
The specific dismantling program and corresponding specific response specification taken is determined.In this way, response message can be made with more after disassembling
The form of a response message segment exists, and can avoid response message data volume larger in subsequent transmission, lead to single transmission
When shortage of data that may be present, it is ensured that the accuracy of data, also, when including the unwanted number of requesting party in response message
According to when, can be avoided and transmit invalid segment, and then avoid the redundancy in output information, invalid information, and then reduce
The data volume of required transmission.
In addition, in this step, the response model can be system default, or the instruction through user to generate
, it is can according to need herein to be set, does not do specific restriction herein.Simultaneously, it is to be ensured that the output of format transformation is believed
Breath can be identified by the called side of external service.As carrying out external service calling process described in the embodiment of the present invention
In, the process for sending request is corresponded to each other with the process for receiving response, and therefore, in above-mentioned steps, the format for inputting information can
It can be corresponding with the format of output information.It is of course also possible to when user is arranged accordingly or has been assigned the instruction of format,
The format for inputting information may also be different from the format of output information, here, not doing specific restriction, progress can be actually needed
Setting.
External service call method provided in an embodiment of the present invention is needed for the prior art when calling external service
Different calling functions is write for different services, and then system resource is caused to occupy larger problem, and the present invention passes through benefit
It is matched with the matching and response model for inputting information with output information with request model, changing the prior art ought need to adjust
When with different services, leads to the problem of need to writing multiple calling functions because inputting the variation of information and output information, reduce
That calls function or program writes quantity, and then reduces the occupancy to system resource.Meanwhile for different input information
Match different request models, different output informations matches different response models, the calling process of external service can be made
It is more flexible, and by the definition to request model and response model, the two models can be carried out into one when needed
The extension of the step demand different with reality, improves the convenience of external service calling.
Further, as the refinement and extension to embodiment illustrated in fig. 1, the embodiment of the invention also provides outside another kind
Portion's service calling method, as shown in Figure 2.
201, according to the corresponding request model of input acquisition of information.
Wherein, the request model is the wrapper mark and the building of first object attribute-bit according to the input information
's.The external service call method as described in the embodiment of the present invention is to be based on implementing on the basis of request model and response model
, simultaneously as different input information needs the external service called to be different, and different external services is carrying out
It is to follow different request specifications when calling.As a result, for call needed for different input information it is different service, need by
It is converted into different solicited messages, so as to it is subsequent call service when can by the system identification where servicing, therefore, this
In inventive embodiments, after receiving input information, it is necessary first to which which kind of request the request model for determining corresponding input information is
Model, to be converted according to the request model to input information.
The method according to this step as a result, it is corresponding according to the input acquisition of information after receiving input information
Request model.Wherein, the request model in the embodiment of the present invention can be according to after different solicited message inputs every time, by with
What family defined, it can also be user's preset in advance according to actual needs, here, having for requesting building time of model not done
The restriction of body, can according to need and voluntarily choose.It should be noted that in embodiments of the present invention, the request model
Building be based on request specification building, including input information corresponding wrapper mark and the first attribute-bit,
In, the first attribute-bit described in the embodiment of the present invention is to input information to be believed according to the set corresponding attribute of request specification
Breath, the attribute information are mainly used for determining the format of input information required conversion in the format conversion process of subsequent step, institute
Wrapper mark is stated when being then for determining that the input information is packaged operation in the next steps, is by which encapsulation
Program or functional function are performed.In other words, in embodiments of the present invention, input information is defined in the request model
Two required important parameters when being converted into solicited message:, can be with according to the first attribute-bit one is the first attribute-bit
Determine that input information needs to be converted to the data of which kind of form when carrying out Data Format Transform；The second is wrapper identifies, root
It can determine according to wrapper mark when information change data format will be inputted, is performed by which kind of program or function.
Therefore, in step, when get request model after, actually determined that input information in subsequent conversion process, institute
The data format of the wrapper and required conversion that need to use.
The method according to this step, according to the different corresponding request models of input acquisition of information, it can be ensured that
Accuracy when the corresponding solicited message of subsequent generation, and then ensure the subsequent accuracy called to different external services.
Simultaneously as different request models is constructed according to corresponding first attribute information of input information and wrapper, it can be true
Guarantor constructs different request models when there is different input information, and then makes outer service call side described in the embodiment of the present invention
Method is more flexible.
202, after receiving input information, according to the data format of request model conversion input information.
Since the language of writing between different services is different, it is therefore desirable to which the input information is carried out format
Conversion, to ensure that the solicited message being subsequently generated can be by the system where external service when carrying out the calling of external service
Or program is identified.It, can basis after the request model for getting the corresponding input information in abovementioned steps 201 as a result,
The data format of request model conversion input information.
Specifically, this step can specifically include: being corresponded to firstly, being obtained according to first object attribute-bit in request model
The first object format of the input information.Then, by the Data Format Transform of the input information to the first object lattice
Formula.Wherein, the first object format is data format compatible with the external service, and the data format then can be
It is determined according to the first attribute information in request model.Due to during calling external service, it is understood that there may be multiple defeated
The external service for entering information, therefore calling be also likely to be it is multiple, needing before calling different services as a result, will be different defeated
Enter information to convert to corresponding data format, i.e. first object format described in this step.
It should be noted that in this step, the first object format can be according to first attribute information
Determining corresponding data format, can also be with the data format of first attribute information, here, specific setting can basis
It needs to be defined when requesting model construction, it is not limited here, can be configured according to actual needs.
According to the method for this step, corresponding first object is obtained by the first attribute information defined in request model
Format, and then the input information is converted to the first object format, it can further ensure to input the data lattice of information
The accuracy of formula conversion, and then ensure the accuracy for the solicited message being subsequently generated, to preferably improve based on described
Request the overall accuracy of the external service call method of model.
203, the input information after change data format is packaged according to the corresponding request specification of the request model,
It obtains solicited message and sends the solicited message, to call external service.
After step 202 change data format, the data format of the input information have converted to external service
Compatible data format, due to what is carried out based on request with response when carrying out the calling of external service, in this step
It needs to be converted the input information of change data format to corresponding solicited message according to request specification in rapid.Since different are asked
Corresponding different external service is sought, meanwhile, different solicited messages has its corresponding request specification, is generating correspondence as a result,
Solicited message when it needs to be determined which kind of solicited message is the input information after format transformation need to be converted into, by which wrapper
It is packaged, as a result, needs to determine wrapper corresponding to current input information from request model first in this step
Mark, and then be packaged according to the mark using the wrapper of the corresponding mark, obtain corresponding solicited message.Specifically
, the process for generating solicited message can be with are as follows: firstly, obtaining corresponding input letter according to the wrapper mark in request model
Then input information after the conversion data format is packaged by the wrapper of breath by the wrapper that gets, obtain pair
The solicited message answered.Wherein, the mark of wrapper described in this step is for when there are multiple wrappers or encapsulation in system
Which kind of which kind of need to call corresponding to external service and corresponding request specification for determining current input information when program
Wrapper.
In this step, the process that the wrapper is packaged the input information after change data format can basis
Predistribution Algorithm or packing rule in the prior art carry out, it is not limited here.But it is ensured that wrapper is carrying out data
Encapsulation process so that when obtaining solicited message, the process of encapsulation is to be standardized according to the corresponding request of input information to carry out,
Accuracy with the solicited message for ensuring to generate.
The input after format transformation is believed by obtaining the wrapper of corresponding wrapper mark in request model as a result,
Breath is packaged, and is avoided when, there are when multiple wrappers or canned program, calling the Problem-Error of wrapper, in turn in system
The accuracy for improving encapsulation process, then makes solicited message more accurate, improves the standard of external service calling process on the whole
True property.
204, the corresponding response model of acquisition of information according to response.
In practical applications, since the external service quantity of calling may be response messages that are multiple, receiving
May be to be multiple, and different response message needs to standardize using different responses to carry out the conversion of format and tearing open for data
Solution after receiving the response message that external service is fed back, needs to be believed according to the response as a result, in embodiments of the present invention
Breath obtains corresponding response model, after being carried out using the second objective attribute target attribute predefined in model mark and resolver
Continuous processing.Meanwhile in this step, the setting of the response model can according to need, according to different output informations
The mode of corresponding resolver mark and the second objective attribute target attribute mark is matched to construct.Wherein, the second objective attribute target attribute mark
Know the parameter of the change data format actually when response message need to be converted into output information.As a result, when receive response
After information, subsequent behaviour can be carried out to the response message by obtaining response model corresponding to the response message
Make, it is ensured that the subsequent accuracy to response message parsing, and then ensure that external service calls the accuracy of feedback result.This
Outer response model can be constructed by way of matching corresponding resolver and the second objective attribute target attribute according to actual needs, really
It has protected when there are different response messages, different response models can be constructed as needed, to export corresponding output
Information, it is ensured that response model it is rich, and then it is preferable to have external service call method described in the embodiment of the present invention
Scalability.
In this step, response model can be according to the resolver mark and the second objective attribute target attribute mark by output information
Building.Specifically, can be constructed by the set information of system default when constructing the response model, it can also
It is instructed with the building assigned according to user to carry out, can specifically be carried out as required, also, construct the response model
Time can be to carry out external service call method described in the embodiment of the present invention preset before execution, can also be with
It is that user temporarily sets according to calling different every time, it is not limited here, can be chosen according to actual demand.
205, after receiving the solicited message corresponding response message, the corresponding response specification of model will according to response
The response message is disassembled, and response message segment is obtained.
After having got the request model in step 204, since the response message received is there are many a bands
The data packet of data, inside include a variety of data in be not all required for the called side of external service, therefore, at this
Step summarizes needs and is disassembled according to the request model to the response message received, specifically, this step may include: head
First, resolver mark obtains the resolver for corresponding to the response message in model according to response.It then, will by the resolver
The response message is disassembled, and response message segment is obtained.
Under normal conditions, there is the case where calling multiple external services when calling external service, therefore work as response message
Quantity be it is multiple when, need to disassemble different response messages according to different response models, due to different dismantlings
Device corresponds to different response messages, and therefore, it is necessary to identify to ensure disassembling device corresponding to current response message by disassembling device
Which is.And currently received response message is disassembled using the disassembling device after determining disassembling device, obtain response letter
Cease segment.
As a result, by disassembling device mark predefined in request model, can determine for disassembling current response message
Disassembling device, and then ensure the accuracy of the dismantling process of response message, to improve outside described in the embodiment of the present invention
The accuracy of service call result.
206, according to the response model, the data format of the response message segment is converted, obtains output information and defeated
The output information out.
After obtaining response message segment, since there may be differences for the programming code between different services, it is therefore desirable to
The format of data is converted, to ensure that the called side of external service can identify the fed back response letter of called service
Breath.As a result, in this step, need to carry out response message segment obtained in abovementioned steps 205 conversion of data format, tool
Body, method described in this step can be with are as follows: firstly, to obtain correspondence described defeated for the second objective attribute target attribute mark in model according to response
Enter the second object format of information, then, by the Data Format Transform of the response message segment to second object format,
Obtain corresponding to the output information of second target identification.Wherein, second object format is mutually to fit with the input information
The data format matched.
It should be noted that under normal circumstances, the data format of output information and the data format of input information are one
Cause, but there is also some special circumstances, if including user setting output information format order the case where, this
In the case of be subject to the format order of user setting.And if user is not when assigning the format order about output information, system
It is identical that the output information, which can generally be defaulted, with the data format for inputting information.
As a result, by the second attribute information in response model by the Data Format Transform of response message segment to corresponding
Second object format, it is ensured that the data format of output information can be identified by the called side of external service, and then be ensured
The accuracy of external service call result.
In addition, it is necessary to explanation, the first attribute information described in the embodiment of the present invention, the second attribute information, first
